Marcinkiewicz's interpolation theorem for Hardy-type spaces and its applications

A series of results similar to Marcinkiewicz's theorem on the interpolation of operators is put forward. The difference from the classical forms of this theorem is that spaces of integrable functions are replaced by some function classes that are extensions of various Hardy spaces.
Some applications of these results to the extension of Carleson's embedding theorem and the Hardy–Littlewood inequalities for analytic functions in Hardy classes are presented.
